A Classic 1950's Commercial for Post's Sugar Crisps. Cheap, but cute.
DISCLAIMER: This video does not represent the quality of major Hollywood cartoons of the time. Nor does it represent the quality of major Tele-cartoons of the time ("Clutch Cargo" didn't air until several years after this commercial, so it doesn't count. Then again, "Clutch Cargo" was already crap by the standards of it's time). Heck, it stinks by the standards of most advertising cartoons of the time. Despite this, it's quite enjoyable.
